They were “predators” and she was their prey.

An 18-year-old freshman at Hofstra University was lured into a dorm from a wild campus frat party, then thrown into a bathroom stall where she was tied up and gang-raped by five men, cops said yesterday.

“This was a predatory act,” said Nassau County Police Detective Lt. John Allen.

The terrifying episode began at around 3 a.m. Sunday when the woman was dancing with Jesus Ortiz, 19, of The Bronx, at a party thrown by the Alpha Phi Alpha fraternity at Hofstra USA — an on-campus club — and he allegedly grabbed her phone.

The Manhattan woman, who a few weeks earlier had started classes at the school, followed Ortiz from the party demanding her phone but he refused, police said.

She followed him into Estabrook Hall, where they rode an elevator to the 11th floor.

“The cellphone was taken to lure her away from the crowd,” Allen said.

Once upstairs, Ortiz’s pal, Stalin Felipe, 19, of The Bronx, “began making advances on her, which she resisted,” Allen said.

They forced her into a stall in the men’s bathroom, where she was tied with rope and sexually assaulted, police said. Soon after, three others arrived, Allen said.

“The victim asked them to help her but, unbeknownst to her, they were friends of the first two,” he said.

All five men took turns raping her, Allen said. When they were done, the men cut the woman loose and “actually had the audacity to ask her if she wanted to go with them,” he said.

The other men have been identified as Rondell Bedward, 21, of The Bronx, and Kevin Taveras, 20, of Brentwood, LI. Another man is still at large, but police know who he is.

Only Bedward is a student at Hofstra. The others were friends he had signed in with campus security, the school said. His room was near the bathroom where the assault took place.

The four men were arrested Sunday and charged with five counts of first-degree rape. They are each being held in lieu of a $500,000 bond and face up to 25 years in prison.

A woman who said she had dated Bedward reported he had been overly aggressive toward her earlier that night, so she left.

Nathalia Fernandez, a 21-year-old senior, said Ortiz had tried to dance with her at the party, but she “thought he was ugly so I said no.”

“It is really scary,” she said, realizing he may have been targeting her.
